SPECIFICATION forming part of Letters Patent No. 510,389, dated December5, 1893. Application fled June 14, 1893- Serial 110,477,574. (No model.)

To all whom it may concern:

Be it known that I, WILLIAM B. HOLLINGS- HEAD, a citizen of the UnitedStates, residing at Bronxville, in the county of Westchester and Stateof New York, have invented new and useful Improvements in Ejectors,'ofwhich the following is a specification.

This invention relates to an automatic ejector, or feeder for use inconnection with disinfecting apparatus and soda dispensing fountains, oras a feeder of liquid hydro-carbons for enriching combustible gas forilluminating purposes.

In the accompanying drawings Figure 1 is a longitudinal-sectional viewof the ejector proper, as provided with a coupling for connecting samewith a pipe or other device, and Elg. 2, a side view of the ejector inconnection with a disinfectant vessel and waterpipe.

This invention consists of two tubes of different diameters, the smallertube A, located within the larger tube B and the annular space betweenthe tubes closed at one end, as shown at o. The outer tube B, isprovided, near the end 0 with one or more perforations, or slots cl; andto provide for securing the device to a pipe, or other article, the saidouter pipe B has an annular collar fformed thereon, so

that an internally threaded coupling-sleeve G may fit over, and againstsame, when made to engage one of the threaded'ends of a thimble h, theopposite end of which is adapted to fit a screw-socket formed in theside of a water-pipe, so that the perforated part of the outer pipeshall project Within the water pipe, as shown in Fig. 2.

The ejector-pipes are preferably curved, or bent, as shown in thedrawings, and the inner pipe, A is made somewhat longer than the outerpipe, the additional length extendng beyond the open end of the outerpipe, as indicated at 2' in Fig. 1. 1

For disinfecting purposes the open ends of the ejector pipes are made topass through an opening in the cap 76, of a vessel Z which is adapted tocontain the liquid, or disinfectingsolution, the smallest pipeprojecting some distance into the vessel, and the outer pipe merelypassing through the cap, in which position it is soldered or otherwisesecured. If the ejector is maintained in an upright position, the liquidor disinfecting solution is forced out of the reservoir through theinner tube, upon the introduction of air or other fluid under pressure.-When the ejector is attached to a pipe through which flows water orother fluid, the resistance of the end extending into the pipe, causes aportion of the fluid to be forced through the perforations or 50 slotsin the outer tube and through said tube into the reservoir forcing outan equal quantity of disinfecting fluid, through the inner tube into theliquid flowing through the pipe to which it is attached. If thereservoir 1, is

inverted the opposite action is attained, 11. e.,

the fluid of pipe, passes into the reservoir through the inner tubeforcing the disinfecting liquid outwardly through the outer tube andperforations or slots thereof.

For use in connection with soda-dispensing fountains, thesirup-receptacles should be arranged on a turn-table, each receptaclebeing provided with an ejector, as abovedescribed, so that the outerends of the ejectors may alternately be brought under the soda-jet ofthe fountain, and sirup desired to be discharged with the soda, into aglass or other vessel.

When used in connection with hydro-=car- 8o bon burners, the hydrocarbonis ejected, by this device into compressed air or steam, by pressureexerted by resistance of said fluid upon the ejector point, and slot oropening in the outer-tube thereof, thereby forcing the hydrocarbonthrough the inner tube into the pipe to which the ejector is attached,to be carried by the fluid passing through said pipe.

This ejector is also adapted for use in connection with atomizers, andother articles not go necessary herein to mention.

I do not desire to confine myself to any special form of opening in theouter tube of ejector, but believe a transverse slot, as shown in thedrawings, the best form for same.

Having described my invention, what I claim as new, and desire to secureby Letters Patent, is

1. An automatic fluid ejector or feeder, consisting of two tubesofdifierent diameters, I00

the smallest tube located within the other, the annular space betweenthe tubes closed at one end, and the exterior tube provided at or 'n earsaid end with one or more transverse slots, substantially as and for thepurpose set forth.

2. An automatic fluid ejector or feeder, con sisting of two tubes ofdiiferent diameters, one within the other, the said tubes connected atone end so as to close the annular space between same at said end; theouter pipe provided near its closed end with one or more openings, orslots, and at a short distance from same with an annular collar, asdescribed, in combination with an internally threaded coupling ring andan externally threaded sleeve, whereby the device is adapted to besecured to any desired object, substantially as and for the purposespecified.

In testimony whereof I affix mysignature 1n presence of two Witnesses.
